VULCANIZER.

SPECIFICATION forming part of Letters Patent No. 636,739, dated November 14, was.

Application filed July 25, 1899. Serial No. 725,067. (No model.)

To all whom it may concern:

Be it known that I, CHARLES L. ALLISON, a citizen of the United States, residing at Leaf River, in the county of Ogle and State of Illinois, have invented certain new and useful Improvements in Vulcaniz'ers, of which the following is a specification.

The object of this invention is. to mend a puncture in bicycle tires by vulcanization while the tire is inflated and on the rim of the wheel.

In the accompanying drawings, Figure 1 is an isometrical representation of my improved vulcanizer. Fig. 2- is a Vertical lengthwise section of the vulcanizer, showing its application to the tire of a bicycle.

My improved vulcanizer consists of the base 1, having the downturned ends 2 and upturned sides 3. A bail-shaped support, consisting of the horizontal portion 4 and uprights 5, is secured to the base. The ends of the uprights are bent in hook form. To the upper portion of the uprights is secured atirerest, consisting of the curved top 6, sides 7, and ends 8. The top and sides extend beyond the ends. A bail 9 has its ends in hook form and engage the hooked ends of the uprights 5. A screw-rod 10 has a connection with the bail and supports a button 11 on its lower end.

An alcohol-burner 12 is placed on the base under the tire-rest. The tire to be repaired is inflated and placed upon the rest, so that the puncture is against the walls of the rest. The bail is connected with the hooked ends of the supports, and by means of the screw rod the button is forced in contact with the inner surface of the rim of the wheel until the tire is firmly seated in the curved top of the rest. The alcohol-burner is then ignited and placed under the tire-rest, when in a given time the crude rubber placed in the puncture will be thoroughly vulcanized and the puncture closed.

So far as known to me I am the first to vul= canize a bicycle-tire while itis inflated and on the rim of the wheel.

I claim as my iuvention-= 1. A vulcanizer, consisting of a suitable base, 1, forming a support for a lamp, abail= shaped strap consisting of a horizontal portion 4:, secured to the base and two uprights 5,1eading upward from the base and terminat= ing in hooked portions at the ends, combined with a tire-rest havinga concaved top 6, said tire-rest being secured to the extreme ends of the uprights, a clamp 9, provided with hooked ends adapted to engage the hooked ends of the uprights, and means carried by the said clamp for acting upon the tire, substantially as described.

2. A vulcanizer consisting of a suitable base 1, having downturned ends 2, and upturned sides 3, a bail-shaped strap consisting of a horizontal portion 4, and uprights 5, secured to and surrounding the base, said uprights terminating in hooked portions, atiresupport having a concaved top 6, depending sides 7, and ends 8, said tire-support being secured to the uprights, a clamp 9, provided with hooked ends adapted to engage with the hooked portions of the uprights, a clampingscrew 10, having a connection with the clamp, and a burner 12, removably located upon the base beneath the rest, substantially as described.
